Abstract

An injector is configured for injecting a fluidic sample from an injector path into a mobile phase in a separation path between a fluid drive and a sample separation unit of a sample separation device. The injector includes a control unit configured for generating a first overpressure in a blocked first partial path of the injector path by a first pressure source, for generating a second overpressure in a blocked second partial path of the injector path by a second pressure source, for subsequently fluidically coupling the first partial path with the second partial path for generating an expansion stroke for releasing a gas bubble in the injector path, and for rinsing the released gas bubble from the injector path.
